Notes
1. Guaranteed by characterization test and/or analysis. Not a production test.
2. Indefinite short circuit protection not guaranteed above 125°C (case)
3. Step transition time >10 µs.
4. Recovery time is measured from application of the transient
to the point at which Vout is within regulation.
5. Step transition time 100 µs ±20%.
6. Tested on release from inhibit.
